The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.

A gaseous refrigerant undergoes compression when 150 j of work is done on it. if the internal energy of the gas increases by 120
zhenek [66]

The heat transferred is -30J

When the gas undergoes compression, work is done on the gas and its internal energy increases.

According to the first law of thermodynamics, the increase in internal energyΔU is the sum of the heat given to the gas ΔQ and the amount of work done on the gas ΔW

\Delta U=\Delta Q +\Delta W

The work done on the gas is 150 J due to compression and the internal energy of the gas increases by 120 J.

Therefore, the heat given to the gas is given by,

\Delta Q =\Delta U -\Delta W\\ =120 J -150 J\\  =-30 J

Thus, an amount of heat equal to 30 J flows out of the system.

At baseball practice, Mason and Alfredo both picked up the same bat and neither would let go until one of them had it for himsel
Illusion [34]

Answer:

Option B. O because the net force was 5 N in Alfredo's direction

Explanation:

To know the the correct answer to the question given above, we shall determine the net force acting on the bat. This can be obtained as follow:

Force of pull by Mason (Fₘ) = 15 N

Force of pull by Alfredo (Fₐ) = 20 N

Net force (Fₙ) =?

Fₙ = 20 – 15

Fₙ = 5 N in Alfredo's direction

From the calculation made above, we can see that the net force is 5N in Alfredo's direction. This is the reason why Alfredo end up having the bat.
